Many tiers have been developed for operation
both with a traveling pick-up baler and with a
stationary baler. Some di?iculties have arisen
probably because the bales formed are relatively
large and unyielding, and the'knots formed have
not been entirely satisfactory. 0n the other

baled through a feed opening in a vertical side
of the baling chamber. A baling strand extends
around a bale along the top and bottom and be
tween the top and bottom of the baling chamber
and has its ends presented to the tier. The tier
is so constructed that as the tying operation pro
ceeds the tier moves downwardly toward the bale
chamber to provide slack in the baling strand or
the amount of strand necessary to produce a tie
without a pulling up of the strand around the
bale.

In operation, material to be baled is fed through

will have reached a position which will‘ have
caused the rod 43 to be pulled downwardly suf

56 from the part 47. When this has taken place,
the clutch 36 will be so conditioned that upon
arrival of the shaft 34 at a predetermiend angu

so as to transmit the rotation of the shaft 34 to
the shaft 35. The beginning of rotation of the

Thus the continued rotation of the bill-hook
from the position of Figure 9 to that of Figure 10
causes the formation of a bight I20 about the
bill-hook 94. Through this movement, the cam
